WASHINGTON — Democrats subpoenaed Attorney General Alberto Gonzales  Tuesday for more documents, escalating their fight with the Bush administration over the firings of eight U.S. attorneys.

The subpoena, issued a week before Gonzales is to testify under oath before Congress about the dismissals, seeks hundreds of documents either withheld or heavily blacked out by his department. The subpoena sets a Monday deadline for Gonzales to produce the documents.

House Judiciary Committee Chairman John Conyers, D-Mich., characterized the subpoena as a last resort after weeks of negotiations with Justice over documents and e-mails the committee wants in its pursuit of whether any of the firings were improper.

Responding, Justice spokesman Brian Roehrkasse stopped short of saying the department would fight the subpoena. But he said legal concerns about violating privacy rights of people mentioned in the documents have kept the Justice Department from releasing them.

SERBIA

Four convicted for 1995 killing of 6 Muslims

BELGRADE, Serbia — Four members of a notorious Serb paramilitary unit who were videotaped gunning down Bosnians near Srebrenica were convicted of war crimes  Tuesday.

It was the first ruling by a Serbian court related to the systematic killings of nearly 8,000 Muslim men and boys in the final months of the 1992-95 war in Bosnia — Europe’s worst atrocity since World War II.

The four Serbs found guilty Tuesday were seen in a video that surfaced in June 2005 when it was shown at the war crimes trial of President Slobodan Milosevic before the U.N. tribunal for the former Yugoslavia.

Families of the victims and their representatives in Serbia expressed dissatisfaction with the sentences, saying they were not harsh enough.

FIGHTING IN BAGHDAD

U.S. forces battle gunmen, female bomber kills Iraqi recruits

BAGHDAD — A raging, daylong battle erupted in central Baghdad Tuesday and four Iraqi soldiers were killed, 16 U.S. soldiers were wounded and a U.S. helicopter was hit by ground fire at the close of the second month of the massive security crackdown on the capital.

Sixty miles to the north, in the mostly Sunni city of Muqdadiyah, a woman with a suicide vest strapped beneath her black Muslim robe blew herself up in the midst of 200 Iraqi police recruits. The attack killed at least 16 men waiting to learn if they had been hired.

The fierce fighting in central Baghdad shut down the Sunni-dominated Fadhil and Sheik Omar neighborhoods just after 7 a.m., the U.S. military said. After American and Iraqi troops came under fire during a routine search operation, helicopter gunships swooped in, engaging insurgents with machine gun fire.

ANNA NICOLE SMITH

DNA shows former boyfriend is the father of her daughter

NASSAU, Bahamas — Larry Birkhead is the father of Anna Nicole Smith’s baby, according to DNA tests, and the late reality TV star’s former boyfriend emerged from a court hearing Tuesday to proclaim that his daughter would soon be home.

“I told you so!” Birkhead said as he jubilantly announced the DNA results after the closed hearing. Then he hugged his rival, Howard K. Stern. Smith’s lawyer-turned-companion has been caring for baby Dannielynn since her sudden death in February.

The hearing left unresolved who will have custody of the girl. Another custody hearing was scheduled for Friday.

Stern said he would not fight for custody.

“I’m obviously very disappointed but my feelings toward Dannielynn have not changed,” Stern said, adding Birkhead can come to his Bahamas home to visit Dannielynn at any time.

SCHOOL SHOOTING

Two students shot inside Chicago high school

CHICAGO — A high school student passed a handgun to a classmate inside a Chicago science classroom Tuesday when it accidentally discharged, striking both in the leg, police said.

One was struck in the thigh and the other near the knee. The two teens were taken to hospital in “critical/serious” condition, the Chicago Fire Department said.

The teen who brought the 9 mm pistol to school panicked, ran outside the building and dumped the gun near the front of the building, said an assistant deputy police superintendent.

While the school has metal detectors, students are chosen at random to go through them because it would take too long to scan each teen, Lopez said. The teen who brought the gun did not go through the device, he said.
